FEEDING DEVICE FOR MANGLES.

Application filed September 17, 1921.

This invention relates to feeding devices for niangles and similarmachines, and has for its principal object to provide a device whichwill feed a row of napkins, towels and the like to a mangle in such amanner that the forward edges thereof will be in ali nment.

/lnother object of the invention is to provide a device of saidcharacter which is operated in time from a folding machine so that thealigning forward edges of the napkins, towels and the like will reach acertain position for action there-on by said folding machine.

Another obj ect ofthe invention is to provide a device of said characterwhich is intermittent inoperation to enable the loading thereon Iof thenapkins, towels and the like. A. further object of the invention is toprovide a device of said character which is of simple construction andpositive in action.

With the above and other objects in view as will be readily understood,the invention will be hereinafter fully described as illustated in theaccompanying drawings and the novel features thereof will be distinctlypointed out in the appended claims.

In the drawings similar characters of reference are used to designatecorresponding parts.

Figure 1 is a rear elevation of a feeding device for mangles constructedin accordance with my invention,

F ig. 2 is a side `elevati-on of the same connected in operativerelation with a folding machine,

Fig. 3 illustrates a holder of the feeding device in normal positionloaded with a napkin,

Fig. 4 is a similar view illustrating the holder in its up position andthe napkin after falling therefrom, Y

Fig. 5 is a plan view to illustrate the forward aligning edges of thenapkins after falling from the holders, and

Fig. 6 is a fragmental view of a shelf of a holder with cloth coveringthe flange thereof.

vWhen napkins, towels and the like .are fed into mangles and similarmachines by several operators, theforward edges of the same are out ofalignment due to the operators being unable to work in unison. Theforward ec ges of the napkins being out of alignment at the. beginning,continue thru serial No. 501,405.

the mangle as started, and when thru the n'iangle, said forward edges ofthe napkins are still out of alignment. in using a folding machine ofthe character disclosed in my application No. 346,742, fil-ed December22, 1919, it is essential that the forward edges of the napkins be inalignment in order that the napkins may be folded evenly. This is thepurpose of designing the feeding device of the present invention. v

Referring to the drawings, l represents the frame of a mangle whichsupports the usual rollers as 2 over the steam sections 3, and a roller4 carrying endless belts 5 Y around a rod or bar 6 serving as a conveyorfor feeding napkins, towels and the like to the rollers 2. l/Vhennapkins are laid upon the belts 5 by several operators standing in frontof the roller 4 asis the usual practice, the forward edges of thenapkins are not in transverse alignment due to each operator not beingable to apply the napkins upon the belts at the .same instant and at auniform distance from the roller 4. As a result of the forward edges ofthe napkins not being in transverse alignment when entering the mangi-e,they continue thru and leave the mangle with their forward edges out oftransverse alignment. In using a folding` machine in connection with themangle, it is important that the forward edges of the napkins when theyleave the mangle should be in transverse alignment, and the presentinvention was designed to feed the napkins into the mangle with theirforward edges in transverse alignment, so that upon leaving the mangle,their forward edges would be in transverse alignment.

Extending from the` sides of the frame l are tip-rights 7 and 8, inwhich is rotatably mounted a rocking shaft 9 supporting a plurality ofdependent holders as 10 having shelves 1l with upturned edges 12 forreceiving napkins 13. The upturned edges l2 are preferably covered withcloth 14 orfother suitable material for preventing slipping of thenapkins. The shaft 9 extends trans versely in the same direction as theroller 4, and the shelves 1l of the holders 10 extend rearwardly beyondsaid roller and at right angles thereto, and are formed on the arc of acircle. The holders l() are rotatably and slidably adiustable on theshaft i?, to which screws at in any suitable position. For,

rocking the shaft 9 intermittently crank arms 1G and 17 are fixed to theends thereof, and to these and to the upper free ends of lever arms 18and 19, which are fixed to the ends of a shaft 20 rotatably mounted inthe frame 1 as at 21, are pivoted links 22 and 2?) respectively. An arm211 is fixed to the shaft 20, and to this is 'pivoted a rod 25, which ispivotally connected to the upper' end of a lever bar 26 pivotallysupported by a short shaft 2?' carried by brackets 2S and 29. To thelower end of the lever bar 26 is pivoted a rod 30, the other end ofwhich is fixed to a bifurcated head 31 for straddling a shaft 32 of afolding` machine indicated by 33. Fixed to the `shaft 32 is a suitablecam 311 in the form of a disc for engaging a lug 35 extending from theside of the head 3l, and having a recess 36 for receiving said lug.llleighted arms as 37 formed integrally with and extending forwardlyfrom the lever arms 18 and 19 tend to cause the lug 35 of the head 31 toengage the cam 34 and retain the holders 10 in their normal positionsfor being loaded with napkins. The weights 38 and 39 may be adjusted toany suitable position upon their arms by means of set screws or anyother suitable means. Each time the cam 34 advances to the properposition for allowing the lug 35 of the head 31 to enter ,the recessltl'thereof, the weights 38 and 39 cause the holders 10 to moveforwardly, and then'they are moved rearwardly to normal position by theaction of said cam. This produces a quick forward swing of the holders10, a slow return, and a rest at their normal positions to give time forhe loading thereof with napkins.

In practice, and when the holders 10 and all parts of the machine are intheir normal positions as best shown in Fig. 2; the operators. standingbefore the roller l, hang damp napkins 13 over the edges 12 and upon thesielves 11 of the holders 10 with their for- 7ard edges 4:0 against thebacks of the holders as shown in Fig. S. As the shaft 32 of the folder33 revolves, it rotates the cam 34e, and the instant the recess 3fthereof is opposite the lug 35 of the head 3l, said lug moves thereindue to the weight-s 3S and 39,' which action causes the holders l10 toswing forwardly to the position shown in Fig. 2l, and the napkins 1 3fall therefrom upon the belts 5 with their forward edges i0 in alignmentas shown in Fig. As the cam 3st continues to rotate, it forces the lug35 out of the reess thereof, and thereby returns the holders l() totheir original or normal positions, and retains them at rest to beloaded by the operators. Each set of loaded napkins fall upon the belts5 at regular intervals with their lforward edges in alignment, and asthey enter the mangle with their forward edges in alignment, they leavein the same relative positions, and as the movement of the holders istimed with the action of the folding machine, each set of napkins reachthe folding machine at the proper time with their forward edges inalignment.
